Problems solved by technology

[0030] That is to say, when the air inlet is provided with an openable and closable valve mechanism, in the configuration that the liquid can enter the air inlet, due to changes in the posture of the container or the surrounding environment (vibration / temperature change / pressure change) etc., the valve body is in contact with liquid, which reduces the reliability of valve opening and closing.

no. 1 Embodiment approach

[0077] Figure 1 to Figure 4 It is a figure for demonstrating 1st Embodiment which is a basic structure of this invention.

[0078] figure 1 It is a schematic sectional view for explaining the liquid container and the inkjet recording head according to the first embodiment of the present invention.

[0079] figure 1 The ink supply system of the embodiment shown in , generally, consists of an ink container 10 as a liquid container, an inkjet recording head (hereinafter simply referred to as a 'recording head') 20, and an ink supply path connecting them. The liquid supply unit 50 is configured. The liquid supply unit 50 can be separated or integrated with respect to the recording head 20. In addition, it can also be provided on a carriage (not shown) on which the recording head 20 is mounted. A supply path from the ink container 10 to the recording head 20 is opened at the time.

[0080] The ink container 10 is generally composed of two chambers: an ink storage chamber 12 a...

no. 2 Embodiment approach

[0107] Figure 5 It is a cross-sectional conceptual diagram explaining the second embodiment in the present invention.

[0108] This embodiment differs from the first embodiment in that, firstly, the acicular body 59 formed on the connection closure member 58 is a hollow acicular body and has a communication path 62, and furthermore, the communication path closure member is formed by a narrow slit in the center. The seam rubber 61 of the rubber member is formed. Also in this case, the connection tube 51 constituting the liquid supply part 50 displaces the connection closure member 58 upward in the figure, whereby the ink container 10 and the recording head 20 become in a fluid connection state, and further, the hollow needle-shaped connection closure member 58 The body 59 is inserted into the seamed rubber 61 that closes the valve chamber 30 and the ink storage chamber 12 , and the valve chamber 30 and the ink storage chamber 12 are communicated through the communication path...

no. 3 Embodiment approach

[0112] Figure 6A , 6B It is a sectional conceptual diagram explaining the 3rd embodiment in this invention.

[0113] In this embodiment, as shown in the drawing, the valve chamber 30 is arranged at the center of the ink container 10 , and the communication path 13 connecting the valve chamber 30 and the ink storage chamber 12 is arranged on the side of the valve chamber 30 . In this embodiment, the valve chamber 30 and the ink storage chamber 12 are in a non-communicative state by the diaphragm-shaped check valve 63 shown in the first embodiment. The one-way valve 63, from Figure 6A , 6B It can be understood that it is a structure opened only from the ink storage chamber 12 side to the valve chamber 30 side. Furthermore, on the pressure plate 14 , the needle-shaped body 41 is provided corresponding to the communication path 13 . In addition, the sealing member 17 is made of a rubber material having a slit into which the connection pipe 51 constituting the liquid supply ...

Abstract

A liquid container is provided which can prevent a leakage of liquid from an air introduction portion under any environment of use and storage and which can maintain a stable negative pressure characteristic irrespective of a degree of liquid consumption. The liquid container includes a liquid containing portion (12), a liquid supply portion to supply liquid from the liquid containing portion to a liquid using portion, a valve chamber (30) having a one-way valve which permits a gas introduction into the liquid containing portion and prevents the liquid and gas from getting out of the liquid containing portion, a communication path (13) to communicate the liquid containing portion with the valve chamber, a mechanism having a function of maintaining a volume of the liquid containing space, and a communication path closing member (55) capable of enabling or disabling a communication between the liquid containing portion and the valve chamber through the communication path. <IMAGE>

Description

technical field [0001] The present invention relates to a liquid container for stably supplying liquid such as ink without waste to a pen or a recording head as a recording unit, a liquid usage device, a recording device, and an inkjet cartridge. Background technique [0002] The liquid using apparatus can be, for example, in an inkjet recording apparatus that forms an image on a recording medium by applying ink as a liquid with an inkjet recording head, by making the recording head move relative to the recording medium while performing ink in the process. A device that forms an image by ejecting ink, or, conversely, a device that forms an image by ejecting ink during the process while moving the recording medium relative to a fixed recording head. [0003] As the ink supply method of the recording head applied in such an inkjet recording device, there is a method of on-board supply, that is, the ink tank as a whole is inseparably or detachably mounted on a carriage or the l...
